WASHING-MACHINE.

Specification of Letters Patent No. 17,377, dated May 26, 1857.

To all 'whom t may concern Be it known that I, ABRAHAM HUFFER, ofHagerstown, in the county of Tashington and State of Maryland, haveinvented certain new and useful Improvements in Washing-Machines; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings and to theletters of reference marked thereon.

The nature of my invention consists in the manner of adjusting theroller concave and iuted cylinder at a distance apart, to suit differentkinds of clothing, and preserving the proper parallel between saidcylinder and concave, the convenience of which will be hereafterdescribed.

' To enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation.

Figure 1, is a side elevation showing the interior work of the machine,in dotted lines. Fig. 2, is an end view also, showing a part of theinterior in dotted lines.

Similar characters refer to like parts in the several figures.

A, dotted lines, Fig. l, denotes the cylinder. B, the roller concave,which is supported at either corner by spiral springs C, C, D, D. Saidsprings rest upon platforms a, said platforms being formed by bendingthe lower extremity of levers E, E, F, F, to a right angle, thussubstantially suspending the concave upon springs C, C, D, D, and leversE, E, F, F.

It may be seen by examining Fig. 2 that levers E, F, lap and that theirends are provided with slots z' in which the upper end of upright rodGr, works, the same being bent to a right angle as seen in Fig. l, thelower end of said rod, G, is provided with a thread which works in astationary pulley tap H. One of these rods and taps are stationed ateither end of the machine, so that both ends of the concave are elevatedat one and the saine time by the aid of other devices which will behereafter described.

Levers E, E, F, F, are pivoted or have their fulcrum at c, c, and bybeing acted upon by rod Gr, the concave is elevated or depressed at thewill of the operator.

I is a pulley which is connected with crank J by means of shaft K.

L is a cord or band which passes around pulley taps H, H, and pulley I.Now by operating crank J, motion is communicated to pulley taps H, H,simultaneously and at preciselyv the same velocity. Hence it may bereadily seen each corner of the concave is elevated or depressedprecisely alike, thus always keeping the cylinder and roller concaveparallel to each other, and preserving the proper angle or pitch of thefeed board. By this arrangement the elevation or depression of theconcave is effected with fa"- cility, ease, and accuracy by simplyoperating crank J as described.

The operation of my invention is as follows: While washing, the cylinderis secured at its lowest point, as seen in dotted lines in Fig. 1, andthe concave is adjusted to suit the articles to be washed, by means ofpulley I, pulley taps H H, rods G G, levers E F, and crank J asdescribed. The whole operation of adjusting the concave being performedby simply operating crank J, as before described.

The novelty of this invention consists chiefly in the convenience andaccuracy of its operation and the general dependence of the devicesclaimed upon each other.

Having thus fully described the construction and operation of myimprovement, what I claim as my invention, and desire to secure byLetters Patent, is:

The arrangement of slotted levers, E and F, upright, Gr, springs (C) and(D) ,connected and operated upon by pulley taps (H) pulley (I), cord(L), shaft (K) and crank (J) in the manner described, for the purpose offacilitating the parallel adjustment of concave (B) as set forth.

ABRAHAM HUFFER.
